..As Ganem reveals in his Perspective, new findings (Bouchard et al.) show that this versatile viral protein is an activator of calcium-dependent Ras signaling, an observation that may explain many of its biological effects...

..We also demonstrate an acute cardiovirus seroconversion event in a child with diarrhea and vomiting, thus reporting for the first time evidence linking cardiovirus infection to diarrheal disease in humans...

DNA binding by Kaposi's sarcoma-associated herpesvirus lytic switch protein is necessary for transcriptional activation of two viral delayed early promoters

..Thus, two potential mechanisms exist for v-FLIP expression, but the evidence suggests that IRES-mediated internal translational initiation on latent polycistronic mRNAs is the principal source of v-FLIP in latency...

..Here we review our computational and array-based approaches for viral miRNA discovery, and we discuss the structure and function of miRNAs identified by these approaches in polyomaviruses and herpesviruses...
